On an error path inside the hso_create_net_device function of the hso

Hi all,
The Energy Model supports power values expressed in an abstract scale.
This has an impact on Intelligent Power Allocation (IPA) and should be
documented properly. There is also a need to update the DT binding for the
'sustainable-power' and allow it to have abstract scale as well.
Changes
The Energy Model (EM) can store power values in milli-Watts or in abstract
scale. This might cause issues in the subsystems which use the EM for
estimating the device power, such as:
- mixing of different scales in a subsystem which uses multiple
(cooling) devices (e.g. thermal Intelligent Power
The Energy Model supports power values expressed in milli-Watts or in an
'abstract scale'. Update the related comments is the code to reflect that

Update the documentation for the binding 'sustainable-power' and allow

shmem_pin_map somewhat awkwardly reimplements vmap using
alloc_vm_area and manual pte setup. The only practical difference
is that alloc_vm_area prefeaults the vmalloc area PTEs, which doesn't
seem to be required here (and could be added to vmap using a flag if
actually required). Switch to use v
Besides calling the callback on each page, apply_to_page_range also has
the effect of pre-faulting all PTEs for the range. To support callers
that only need the pre-faulting, make the callback optional.

this series removes alloc_vm_area, which was left over from the big

This is a series of fixes created during porting a device driver (these
patches will be released soon too) for an SPI device to the current kernel.
The two most important are
spi: spi-s3c64xx: swap s3c64xx_spi_set_cs() and s3c64xx_enable_datapath()
spi: spi-s3s64xx: Add S3C64XX_SPI_QUIRK_CS_A
Check return values in prepare_dma() and s3c64xx_spi_config() and
propagate errors upwards.

Increase timeout by 30 ms for some wiggle room and set the minimum value
to 100 ms. This ensures a non-zero value for short transfers which
may take less than 1 ms. The timeout value does not affect
performance because it is used with a completion.
Similar formula is used in other drivers e.g. sun
Add a proper helper to remap PFNs into kernel virtual space so that
drivers don't have to abuse alloc_vm_area and open coded PTE

Make sure the cur_speed value used in s3c64xx_enable_datapath()
to configure DMA channel and in s3c64xx_wait_for_*() to calculate the
transfer timeout is set to the actual value of (half) the clock speed.
Don't change non-CMU case, because no frequency calculation errors have
been reported.

When vfree is called on such an allocation it will put one reference

Hi all,
The Intelligent Power Allocation (IPA) estimates the needed coefficients for
internal algorithm. It can also estimate the sustainable power value when the
DT has not provided one. Fix the 'k_i' coefficient which might be to big
related to the other values, when the sustainable power is in
The sustainable power value might come from the Device Tree or can be
estimated in run time. There is no need to estimate every time when the
